Cubic interpolating plane curve or space curve

**Library:**Simscape / Multibody / Curves and Surfaces

This Spline block creates a continuous spline curve based on cubic interpolation
between the specified points. The curve can be two dimensional, such as a planar cam
profile, or three dimensional, such as a roller coaster track. The dimension of the
spline depends on the dimension of the coordinate matrix. An `n-by-2`

matrix specifies a 2-D curve in the *xy* plane. An
`n-by-3`

matrix specifies a 3-D curve. All the coordinates are
resolved in the local reference frame of the block. Moreover, according to the specified
end conditions, the curve can be either open or closed.
